Dental fear is often associated with experience of pain, unpleasant sounds and uncomfortable vibrations caused by dental drills. Therefore patients welcome alternative, less painful excavating methods such as lasers, sandblasters and chemomechanical systems. The aim of this study was to compare a chemomechanical caries removal system (Carisolv) to traditional drilling with regard to patient acceptance and time consumption as well as the six-month success rate of fillings. Ninety-two primary teeth in 46 children were included in the study. From this study, the following conclusions can be drawn: patient acceptance of Carisolv-treatment compared to drilling is excellent, since 65% would choose Carisolv and no one drilling when treated next time. The dentists rated patients' degree of pain significantly lower in Carisolv situations than in drill situations. Time consumption is significantly higher when excavating with Carisolv (6,7 min.) than with drill (3,3 min.). The durability of fillings six months after treatment is equal in the two groups.
